Vacuum boards, steam generators, and boilers for sewing machines. These two formidable allies cooperate to help you finish your sewing projects flawlessly. All sewing machines require these garment maintenance supplies. Boilers for sewing machines are tiny appliances that produce steam for use with a steam iron. Steam from a sewing machine's boiler can be used to press seams, remove wrinkles, and shape textiles without any effort. Fabrics can regain their silky smoothness and wrinkle-free appearance after being run through a steamer, which releases a forceful blast of steam that relaxes the fibers. These portable tools are a godsend for seamstresses who need to iron out creases or refresh fabrics quickly.
